If the bow-thruster fails you can maybe try kicking your way :-)
Actually I am not a big fan of bow-thrusters. I usually consider it an unnecessary weight in the bow, where you really want to minimize weight. And a skilled skipper should be able to handle the yacht without one.
It becomes tricky, however, when you have twin rudders and a single engine. In this configuration the engine will not generate any water flow over the rudders when the yacht is still. Which means that there is no way to create a turning force on the boat unless it is moving. This is a little too limiting even for a skilled skipper I think, so the Journeyman will get a small retractable thruster.
